TechCrunch is reporting, from sources including one "close to Google," that an official Google Voice application received an App Store approval, allowing a full-featured Voice client to run on iPhones. If their report is correct, the app is already approved in its current form, but Google is working to implement multi-tasking and other iOS 4 features. Apple's initial rejection of the Google Voice app spurred our rather harsh take on the drawbacks of iPhones, and this is a nicely curative step. Let's just hope it's true. [TechCrunch]
